Sorry for coming off rude, its just a very common question here. I know it a concern for most people who are getting started with wakesurfing because they are used to wakeboards.
The truth is that there is a huge difference in the ride depending on the construction, and that compression molded boards are pretty much designed only to be durable (the Inland Surfer Squirt is an exception). They (compression molded boards) may severely limit what is possible on a wakesurf which can skew the riders view of the sport of wakesurfing (this is VERY common. there is so much more to the sport than standing in one spot while drinking a beer, but its hard to do much more on these boards).
So to answer your original question: yes glassed boards are fragile, so you should probably go with a compression molded board. When you feel like making the switch to a glassed board it would be a really good idea to keep the board in a padded bag or at least a board sock at all times.
