I would consider buying a '1st generation' shaped ski - that would be late 90s/early 2000s. NOS stuff pops up on fleaBay all the time. Those skis were not nearly as radical a jump from straight skis as what is in the shops today. Something like these K2 Fours would be perfect (although unless you're very tall/heavy you would want 188 or even 178, not these 198s!). These skis were revolutionary at the time and they will be for you now after a long layoff. You may have no need or desire to buy anything beyond those. I still love skiing on the 1st generation stuff, although I've got newer skis too.

Also, Mark's pole trick is good advice. We used that same basic exercise many decades ago when I was instructing.
