Before i make my second trip to the lake, i wanna get some bunk style guide-ons.  Which ones work better in guiding the boat sqarely on the trailer:  a (low profile)5' board with brackets that mount in front of and in back of the trailer tire, or a single bracket with a 2' board that mounts towards the rear of the trailer.  Im leaning towards the low profile 5' board set-up.  What do you guys think??

Depends on the boat & the operator

I'm not sure what kind of boat/trailer you have or the specific issue you are facing.  But, since you mentioned the 'second time' you take it to the lake it reminds me of my earlier problem.  My tracker came with pretty small trailer guides, and the first time I went out there was a bit of wind.  I put the trailer in too deep and this ended up with the boat going on straight, but then floating off center when I would try to pull the boat forward.  To fix that I found that getting the bunks completely wet, then pulling forward so only the first foot or so of the bunks was under water, I can approach the trailer with just enough juice to keep it straight and glide the boat on.  This way, as long as I hit it straight it stays straight.  My hull has ridges that corespond to the trailer bunks, so if you are right or left too far the hull will not sit straight/can't hook up the transom saver, etc.  Good luck and let us know.

Get the long ones.  As stated above, if the ramp is steep, the boat WILL have a tendency to float out over the short guide-ons causing much problems when trying to pull trailer/boat out of water.  I fish alone and these side bunks have been a real winner for me.

I purchased the ones that BPS sells.  Galvanized, very strong.  Have had them for 5.5 years and no problems whatsoever.  Think they are on sale now for around $99.  If you launch/retrieve ANY in wind and tidal/river currents, you will look at this as money well spent.
