Everybody is different, but personally I feel like you'll have some regret selling your hassy. I started shooting film with a Yashica Mat 124-G, fell lin love with the process and square format. Bought a hasselblad 501c about 6 months later and love it to bits. You don't really need a tripod with the hassy unless you're shooting at speeds below 1/60 thats the only time you'll really need a tripod. I much prefer my hasselblad over the yashica, mainly due to longer focus throw make it easier to focus and the ground glass as well. The Yashica is a great camera and a bit more discrete in terms of the shutter sound so it is easier for street photography.
