Doug, my TLD20s and 25 work just the same as your 25. The only way to put them in free spool is to pull the lever all the way back and click it over the button. IMO they are designed that way to prevent accidental "free spool".
I believe the general rule for lever drag reels is to set the drag so you get 25% of the line's breaking strength in "strike". This will equate to rougly 33% of the breaking strength in "full strike". With 30 lb. line you sould set the drag so you get betwen 7 and 8 lbs. in the "strike" position. That will give you about 10 lbs. if you need to push to "full strike". That is how I set mine, and then I back off just a tad when I set the rod out. As soon as a fish hits...full strike and set the hook!!!! Unless it's a marlin, then you hafta let 'em run a few seconds to get the bait turned in his mouth...then you whack 'em!!!!!!
