we saw this mass move to inlines a few years ago. around here, i've seen most move back to spinning reels. Even on the TV shows most have also switched back.
Inlines solve line twist, but i think many have found that line twist just isn't really that big of a deal in majority of situations. The disadvantages of poor drag systems and slow drop rates are the biggest culprits.
Catching fish on a free spooler is definitely fun if you aren't worried about losing fish.
I started with okuma like 6 years ago, bought every inline under the sun. i mainly use my spinning reels.
