I'm hoping to begin running some IV+/V- water next year and want to pick up a boat suitable for those needs. I'm wondering what people think of boats like the Diesel and H3 which claim to be good for river running and creeks. What's considered the disadvantage of using full on creek boats for river running? My understanding is these hybrids tend to have sharper edges than creek boats which may help manuverability but increase the risk of accidently catching an edge. Other issues? I've been in an EZ, is there is big transition period into a creek boat? Thanks.
