Firstly, I'll admit I have a fondness of the Y-Wing, particularly with the BTL title. They've served me well. I've been working with a BBYY force primarily armed with ion cannons and I feel it deals with the big turrets. It hits hard, it's tough... but the lack of maneuverability is an issue and arc dodgers have been a problem.
Thought patterns: I've considered three approaches so far.
1) YYYB (94 points as stated here)
Two Y-Wing Golds with BTL and Ion Turret
One Y-Wing Gold with just Ion Turret
One B-Wing Blue with Ion Cannon
2) YYYA (100 points)
Three Y-Wing Golds with BTL and Ion Turret
Tycho with PTL, Autothrusters, Expert Handling, and Chardaan Refit.
The first list gives me some limited turret usage to ward off fighters. It could happen.
The second gives me a fast pain in the neck to keep an arc dodger occupied. I lose some of firepower and durability, but I certainly pick up something in evasiveness and speed and eliminates the 'entire force is vulnerable to a single tactic' problem I had.
3) YYYAA (99 points)
Three Y-Wing Golds with BTL and Ion Turret
Two A-Wing Protos with Chardaan Refit
This one the A-Wings strike me as blockers and decoys... with out Tycho's abilities and extra maneuverability though I suspect they won't actually last that long. These could easily be swapped out by a pair of Z-95s with some points left over which would likely be of better value in this case.
Any other suggestions?
