New setup... please help!

Hi, I'm looking for a new setup and have been reading equipment reviews for a few weeks now. I've been playing for about 4 years and am getting to a decent level (play in a local club league) and at the same time I'm still working on fundamentals. For the past two years I've been using a stiga oc cr wrb with xiom vega asia on both fh and bh. My blade is pretty light, I think 78grams and was wondering how different a heavier blade would be as I'm looking to get a touch faster? Also, I've only played harder sponge rubbers (current rubber is the softest yet) but am interested in trying a softer sponge, wondering about advantages/disadvantages? I tried a mark V rubber a couple times and struggled controlling pushes around the net, which scared me into less bouncy rubbers. I'm basically an allround player and still working on skills, I'd like to get a new set up that is a touch faster and still controllable and good for continuing to improve skills. I was thinking wood 5 ply ALL+ or OFF- blade and rubbers that are good for allround and my skillset.

blades I've been considering are:
- stiga celero (is this to much of a weight change?)
- stiga intensity nct (is this too fast?)
- cornilleau hinotec off-
- butterfly primorac
- butterfly korbel (is this to much of a weight change?)

rubber considering:
- butterfly rozena
- xiom vega europe
- xiom vega pro

Based on what I've read, if I were buying today I'd get the stiga celero with butterfly rozena rubber. Thoughts?

I'd like to make a change but not one that will be so drastically different that it takes a long time to get used to. Any info/suggestions about listed equipment or other suggestions would be appreciated.

Cheers
