yeah, at first it won't make much of a difference, and it will help you appreciate a tower once you can ride behind one. I learned all the basics, including a back roll and tantrum behind the back of an I/O.
Your boat will get anything everything you want to do, done. You will want to go on a bit shorter rope than what you hear or see others doing behind towered v-drive boats, maybe 50-60ft. Wakeboarding isn't about the boat, it's about the ride.
