Hey Brandon, i don't know your level of training , however at those lengths you should bare in mind the weight of the sword if you will use it for iai. I learnt the hard way training with a 1400 grams sword for 9 years , gave me all sorts of issues with tendonitis etc...my current sword weighs 1200 grams. Its a good weight for iaido and tameshigiri. Just my few thoughts
