LF Fish size help?!

I was thinkin of getting a LF fish to add some more fun to my inverts and spins. I weigh 170 and the sizes of the fish are 125 and 129, etc. on the 125 my weight is smack on the end of the recommendation weight range, however the 129 is only like 8 cm shorter than my ps3. Will i notice the difference? or should i take my chances and go smaller? Which size would i have the most fun on?

Go smaller. The Fish is designed to be ridden 10cm shorter than you normally ride. I am 185 and have a 129 and it is plenty for me. I love that board...the pop is incredible and it spins great.

im about 170 and i ride the 133, i just think having the fish any smaller wouldnt give it the pop I'm looking for even though i have ridden the 129 before and it worked just fine [ even though that was two years ago ] hahaha.

I know you ride it 10cm shorter, I am just wondering if there would be any difference riding on a board I would be at the top of the weight range for compared to being in the middle of the weight range.?
