I would suggest that if you haven't already done so, follow Norm Whittle's excellent tutorial in this forum. His recommended settings are a great starting point.
I flew , quite extensively (and trouble free), a 66 ounce SV-11 on 64' of line. The new owner has similar success.
Two things I notice with your setup. The Ice Lite 50 will be marginal with an E-Flight 32. I used a Phoenix 45 because it can take a 60AMP spike. The Ice Lite 50 isn't rated that high. Unfortunately, Castle Creations discontinued the Phoenix 45, so my guess is that you'll have to step up to something in their newer 75 series. There is an additional weight penalty of about one ounce.
I first used a 4S 3900 pack and later switched to a 5S 3300 . You mentioned that you run a 5S 2700 pack which, in my experience, is rather small for the job. I doubt that you would be treating that pack well if you exceed 4 minutes as the Power 32 is a "big block" and consumes a lot of battery. You want at least a 5:45 minute flight from the time of spool up and ideally, you should land with the battery showing somewhere between 20-25% left.
Below that, you are looking to shorten the life of your lipo.
Good luck.
