TigersharkI held off on jumping into your thread until you finally mentioned the Tigersharks. I have the 10' w/ switch and just did a week on them on eastern hardpack/ice, some slush, and finally one day of some loose/soft snow.
I'm male 5'9" 168# expert former racer and was on the 168s. These skis totally rocked on hardpack...the grip is incredible, they like to run but I found short, quick turns no prob too...they are not dialed into long GS turns even though they like to go there.
I did find them a bit squirrelly in looser snow, although I only skied them that day with the switch on b/c it's not like there was any serious powder. On hardpack I much preferred them w/ switch on, and the power, stability and edge hold were all much stronger in "on". But a lighter touch, more finesse skier might well prefer "off". I just found that in "on" mode, they could handle speed and power and also were not at all difficult to initiate when skiing slowly/leisurely (e.g., following my 5 year old down green runs). They were just remarkably easy to ski in "on" while also really shining when put to work at high-ish speed carving....and with all sorts of turn shapes.
I didn't get into any serious bumps with them 'cause there weren't any around, just some small late day wet snow bumps that one day after a 9" snowfall. I can tell that soft edge drifting in bumps will be no problem -- they're not hooky -- but it's not what they make you want to do on them and they are pretty stiff, and so I doubt I will love them in serious bumps in "on", but switching to "off" may be just the trick. Hope so! They have a lot of shape, though, so not likely to truly shine in bumps.
I have not skied the AC3/30 or 4/40, so can't compare. But I suspect the 40 would do quite a bit better in soft snow than the TS -- again, the TS has a lot of shape and even a few inches of loose wet snow took them a bit out of their game. But on hardpack, just awesome, and a perfect groomer eastern ski for a person who loves race skis but doesn't want to be too locked in to either SL or GS turn shapes.
So net-net, I bet you'd love the TS for the bread and butter hard snow skiing at Jay to replace your SL racetigers, but they probably aren't the right 2nd ski to use instead of the racetigers for soft snow days and in bumps, trees etc.
