You switched out the bearings on a Calcutta? Was it a worthwhile difference? I'm tempted with my Luna but it's one of those why fix something that ain't broken.
Personally I'm not the best caster, but anything about 3/4 to an ounce, I can cast pretty much as far as my spinning reel but anything lighter definitely my spinning reel takes it, especially 1/4 ounce spoons, never mind spinners. I never expected to cast my level wind like I can with a spinning reel.
Mind you I have fireline on my spinning reel and 17lb mono on my levelwind but still, for me, the spinning reel will bomb farther.
