I've been waiting to comment to see if someone with a David 70 would give you their opinion ..... my David is a 90. Most times my 90 is wide enough for the things that I normally weave, which are tea towels or items that width. However, I've been very thankful that I've had that extra width - and sometimes wished for the width of my old loom, when an idea has popped into my head that I would like to weave something wider - like a shawl, baby blanket as a gift, or right now when I've been challenged to weave cloth for a project. That extra 20 cm is just sitting waiting for the moments when I'm very thankful it's there. I don't think that the weight would be an issue and I don't have any spare space around my loom, but that works in my situation. I find the David the perfect loom for me to handle with my ageing body. I hope this input helps.
