I must first issue this disclaimer....everybody has an opinion, that doesn`t make them right.

That being said, here is my opinion.

Sure lock makes a great slider sight. Definately worth checking into.

Custom Bow Equiptment(CBE) makes slider sights that are as good as any, better than 99% of the sliders on the market.

I have had several different sliders since 3-d archery was thought of, and there is nothing worse than finding that something moved on your sight/scope setup.

If you go with a sureloc, or CBE, those problems are history.

There may be other brands out there that are really good now, I would not know, because I have 3 CBE tech lite sights, and they will out live me!
They are that good!

I have never even used a sureloc, but from looking at them, I would not hesitate to try one.

As far as scopes go, that is more of a personal preference thing. As long as you get an aluminum housing, and a 10-32 rod, they should be fine.

I use a G&B ultimate eagle, with a zeiss coated 3x lens for 3-d.

Hope my feeble opinion helps, and be sitting down when you find out how much one of these setups cost.

It will be cheaper in the long run than working your way through all the inferior stuff then ending up here anyhow.
