ok dude so you went from suspects and invaders to tnks, which are all about the same widths (not exactly, but fronkley its ganna be kinda hard to tell the difference). in terms of pow, tnks will float even less than invaders and i would assume that suspects would float just as badly if not worse than either of those two because they are stiffer by far. at your weight your ganna want the softest skis possible because they float in powder better, will feel easier to flex, and will still feel fairly solid on landings. although im a bit biased, i would say your best bet would be line, or maybe arv. line anthems or lizzys is what i would ultimately recommend to you, depending on which width sounds better to you.
hope al this helped man!
