By all means fish those pretty reels! That's what they were made for. Abel guy from way back, mostly TRs and now SDF. Never had a problem. Regarding tests, never heard of a single fish being lost due to "start up inertia" and some of the reviewers admit same.
I have been a staunch cork drag guy for a long long time and have shied away from sealed drags. But after talking to Jeff Patterson at Abel and the testing they did with their's in the Keys I decided to give them a go. I have two 9/10 SDSs and they have been my go to reels for redfish the last six months or so. So far I love them but they havent' been tested really. April in the Seychelles will be the real test.
