The feel you describe is a result of the high letoff on your bow and is to be expected. A string with 15 pounds tension on it will not leave your fingers with the same authority that it would if it was under 25 pounds tension - like you'd have with 65% letoff.
But there is a way around it, if you want to give it a try.
When you begin getting a feel for the release, try letting the string roll from the creases of your joints out about halfway onto the pads of your fingertips before you begin your pull-through to release. With the low holding weight, you'll have plenty of strength to retain the string with no problem and there won't be so much finger surface for the string to drag across.
Just remember that -unless you've got extraordinarily strong fingertips- you'll have a hard time letting down without working the string back into those creases at the joints.
Have you checked to see if BowTech offers 65% letoff modules for your bow?
Edit:
Also, when it comes to gloves and tabs, I like a tab made of thin cordovan leather or one of the old red and black Black Widow tabs with superleather face. For hunting, I REALLY like using a Damascus glove. It's thin enough that I have excellent feel and control over the string, but thick enough that I can shoot all day and not wind up with sore piddies.
