Most of the TC bases are fairly short so you don't have a whole lot of flexibility in mounting position. Some of the ones that do require drilling and tapping 2 additional holes. A longer base like that gives you a lot more flexibility regarding scope mounting position.
I really liked the Virgin Valley aluminum bases but I think those have been discontinued. They still offer steel ... heavy. For a scope I used an old Weaver K2.5 on the .32 mag and .357 Maxi barrels. That was good. Years earlier I put a Leupold 2.5-8X on a 21" TC carbine in .17 Remington. That scope was always too far back and required some shooter contortions.
Anyways, I think whatever problems you run into are better addressed by changing to a longer base even if it means drilling additional holes.
