RE: SLIDE SIGHTS
Not sure what your budget is. I think you mentioned around $70 in the past.
I don't know about a slider as I haven't really been in the market for a new sight even though I picked up a Copper John's yesterday. Makes sense, huh?
As far as looking for a site goes, go to Google and type in the sight you are interested in and LH behind it and it should pull up where they are available on line. i.e. "HHA Optimizer LH"
If that doesn't work put a $ sign behind it.
Good luck and happy "sight" hunting!
