Thoughts on running 4s?

I'm thinking about switching to a 4s setup on my trex.

I'd end up ditching the JGF motor and going with something like one of the scorpion motors at the 4500ish kv.

Questions:

How bad is the weight penalty? Does it cause any major CG issues?

What esc would be recommended(amperage)? It has to be a CC esc, because I'm spoiled by the Castle Link. I'm running a Phoenix 35 right now, would a 45 cut the mustard? Or would I want larger than that for a safety margain?

I'm assuming the woodies aren't safe at real high headspeeds. I've been running 2800 on mine for many flights now with no issues, but I'm unaware of their maximum rated rpm. Will v-blades be safe up to(or exceeding) 3300?
