Dude I was just about to post. After talking to skylar from swfa, thanks again skylar, I pulled the trigger on one. I figure i can't lose money on it and he said glass is comparable to the newest vx3i line. I like the style of the reticle, but wish subtension data was available. Gonna go on a 6cm that's getting finished up this week.
What swayed me:
1. Vx3i glass is pretty good, not tier 1 but good enough to shoot LR with for me. Glass is subjective so ymmv
2. Has a zero stop
3. Christmas tree reticle is handy
4. The Dev-L reticle has an anti cant feature (pretty cool imo)
5. For a sfp vx3i 4.5-14x40 it is same price point and this will be used for LR and need FFP.
6. Cost! It's half the price of the xtr-ii which I like, half the cost of the pst and bushnell elr.
7. Comes with coupon for free custom ballistic turret. I'm guessing like cds.
8. The few reviews I found were positive.
http://www.snipercentral.com/sig-tango-4-4-16x44mm-full-review/9. Designed by ex leupy folks.
10. Warranty is supposed to be on par with leupy and vortex.
11. Auto shut off illumination, not that I use illumination often.
Don't care for initially:
1. Color but that can be changed
2. Lack of track record
3. A few reviews said zero stop was complicated???
4. No idea what subtensions are and can't find anything on the web
5. Read has short eye relief but that could be user.
Will do full review when I get it. Will compare to Mark 6, pst, weaver tac, xtr and tx5i
