Anyone use bunk guide-ons for 175?

[kchaudha]

Not too long after I got my 175, I learned the optimum trailer depth in the water to ensure the boat gets back on straight.  Generally works well except for this one lake ramp that I go to that must be crooked or something - the boat always sits off to the left.  It's agonizing to get it to sit straight when loading back on this ramp and I end up avoiding that lake as result (which is a shame!).  As much as I thought that bunk guides are generally unnecessary, I think I may be happier to just throw some on and see how much they help in this situation.
My question is whether anyone has them for their 175 and which ones you used.  The 175 is not very wide on the trailer and it looks like a lot of the guide-on bunks stick out wide and may not hug the boat without some modification/bending.  Anyone have experience with this?
Thanks

Sometimes my 170 comes out of the water a little crooked on the trailer and I do have the wide guide-ons on the trailer.  I just push the back of the boat over on the trailer  - they don't weigh that  much.  You can also put guide boards on the sides of your trailer if you want.

My 175 sits on only 3 of the 3 roller sets.  Woops?  Its just about half an inch of less off the 3rd back left roller set.
