uni pylons?

i have an I/O and im looking at pylons the pylons in barts only have 2 bars in the back http://www.bartswatersports.com/catalog.asp?C=148&P=541 and the ones in overtons have 4 bars http://www.overtons.com/cgi-bin/overtons/order/pdetail.cgi?15762++1Z7A

I'm actually building mine. It is much cheaper.

really how ?? can u semd me blue prints , cost?, difficulty?

I built a pylon in like 1 hour i had a smaller one existing on the boat (an outboard) it was located at the back like the one in the firdt link all i did was got some pipeing cut holes for the supports at the back and attached it very eeasy im not using a rope and it works fine ill get some pics later

not using a rope to the bow that is. i recommend building your own for anyone on a budget it is very easy and if you have one alredy there but its small it will be a very easy project
