Go ahead and get the 25. The TLD 25 is probably the best all around offshore reel for the money. It has plenty of capacity, drag pressure and is very light. There really isn't many things you can't do with it.
Beats the hell out of a penn 4 or 6 ought any day. I have a few on Tuna sticks, and it makes a great light weight combo, and I bet there are lighter rods out there. Its nice after a few hours of bottom fishing.
