Share a similar issue and favor equipment that blends wet/dry for THS. I've rolled all the IQs and love the IQTS and agree i didn't see much difference with the Nano. I was hoping to replicate the original IQ wasn't available long.
Not that I need a stronger ball than the IQT, thoughts on Hyroad Nano for OP? Never rolled one but seems like it would be a better roller than the IQT.
