It's been awhile since I trolled regularly for stripers but followed the old timers rule:
If you think you are going as slow as you possibly can, you are going too fast. This is especially true early in the season when the fish are more lethargic. Don't have too much experience with the stretch 25s but can't imagine it's too much different than the 30s. Key is also making sure they are tracking correctly at the right depth. Ie, just a few feet off the bottom.
Enjoy it now bc when the blues come in you won't be trolling them anymore
