I think have the option of both oHRM and chest strap is very versatile in my opinion. In terms of price point, it's $50 more for the between the 230 and 235 so not too steep in the additional cost of having the oHRM.That's pretty much the way I think about it. It's easy to functionally disable the optical HRM if it irks or disappoints, it's easy to get over any regret of an (additional) expense of $50 when that emotional response is just in my head and solely in my control, but it isn't nearly so easy to try and bolt on a 24×7 function for that price if I want to experiment with it later.
