WW'ers rock! It is a great resource and repository for info. Cool, on the shuv's. If you aren't dead set on the them that open's up more options.
You're weight is just a bit high - NOT calling you fat!!!
But some of the boards have a 180 pound cutoff...I can remember reading somewhere that the average ocean surfer weighs 140 pounds!
My bigger concern is your height. Tall folks have a wider stance and I have fund don't like the ride of smaller 4'6" boards that fit their weight. Personally, I would recommend you look at 4'10" up to around a 5'4" for your purposes. You don't really need the extra length so much, but I think it will help you accomplish 2 things. One is that the extra length (5' 'ish range) will accomodate your wider stance and also this extra length will assist with speed. This length issue is why I am excluding a few other boards (Trick Boardz, Calibrated, etc) I am going to make one exception and include the IS Yellow. The yellow is significantly shorter, but is much wider and as such, has about the saame surface area as the other boards in this general size. Plus, it's flat running length is about the same as some of the others so that the stance issue isn't so much of a problem.
Either the IS Blue - the new 5'4" model or the IS Yellow would be good options for you. I would suggest that you'll find the Yellow easier to throw surface 3's with, airs can be achieved, but since these boards are heavier they will make it harder.
SS's has some good options also. Threhser Shredder is a good all around performance board. 4'11" length will fit your stance and it does have down the line speed. A little slower than the IS Blue and Yellow, but not by much. SS also offers the Piranha, but the Thresher is the most performnace oriented of the lineup for your size.
The WP Composite X 5-oh, is a good solid surfstyle board that comes in a stock size. This board HAULS, extremely fast and is the lowest cost of the bunch at $299. Faster down-the line than the IS Yellow and SS Thresher, comparable with the IS Blue.
The IS Yellow and SS Thresher are the two most responsive rail-to-rail, then the WP Comp X 5 and finally the IS Blue.
Storage becomes an issue for some folks. The WP comp X, without traction will fit in a standard wakeboard rack, the IS's fit in some, but not mine and the SS will not.
IMO, the SS is the most complete board of the bunch. Nose and tail protectors, available in various colors and complete traction. Tough to beat.
For all around performance on a budget...the WP Comp X is the clear choice.
For ease of location, good solid performance and solid construction...the IS boards, are tough to beat.
IMO, the boards listed will perform better than an Oogle.
The Walzer Alpha in a 1" Large is another great board, but IMO isn't as fast down-the-line as the other boards. Especially as your wake diminshes with speed. Nothing against the Walzer, but for this situtaion, tall - wide stanced rider, not the best wake, attempting to ride faster to lengthen the pocket and a desire to ride more aerial/slashy...I went with the other boards.
Now comes some of the additional refining points.
You mentioned that cost wasn't really a major issue, the cheapest is the WP, the rest are all in the 500+ range. 200 is a LOT of "not important" in my book.
I would think that FINDING the board is a concern and currently, the IS's have the broadest market distribution...and you mentioned, I think, that you can find them locally.
The last consideration is storage, if you don't have a surf rack, and this is a HUGELY important option, only the WP and IS's fit - and the IS's might be a squeeze.
All of the boards have some graphics, the SS gives you 4 color choices, the WP 2 and the IS just 1. That may be important to you.
So...that's my input, you'll have to keep us posted and give us the decision criteria when you pull the trigger.
Best of luck!
