Ok great! So, it does appear trying to install the Evo .61 would be hack job. Just a bit too big, I guess.

Ok, then, looks like I will pick up an Evo .52 in next couple days. Yes I like the look and feel of the Evo. APC 10x6 it is, I'll pick up some spares too.

Thanks for the tips! Stay tuned for progress posts!
