I agree with Marty on this one. Though, I haven't totally punched a hole through, I did put a good tear in my old Aire Ocelot. Never punctured or damaged my driftboats. Some scrapes were about it on the driftboats. And I too have beat the living crap outta all mine over the years. Onto drag ability, it's all in how much weight is in the boat at the time and how heavy the boat is. My old Eastside slides nicely, but it's alot lighter then most newer glass boats. My old alumaweld driftboat I had was a bear to drag (even with the gluvit). Mind you, I LOVE inflatable boats. Especially the cataraft grade boats. But I've always had a preference when I'm really hardcore fishing to use driftboats or river suitable prams.
