5100s aren't bad. They are just one tick above the bog standard 4600 OEM replacements -with the ability to ratchet in some lift as the main difference. They are budget shocks, and there's no way of getting around that. The nice thing about 5100s? They are tough as nails, I've personally never seen someone blow one.
Once you've ridden in Icons or Kings or ADSs or Foxes, etc you'll see what I'm talking about. The difference is night and day. The downside? The price is also night and day.
So my point remains, if you don't plan on utilizing the 5100 struts for their lifting capability, you may as well just save your money and get a fixed length strut.
Then again, you seem very determined on the 5100s, and I'm certainly not going to continue to talk you out of them. I think you'd be happy with them, at least for awhile. But, for just a little more money, the 6112 is a huge upgrade, and a great midway point between the budget shock world and the awesome 2.5" shock paradise.
