With the push/pull throtle and friction tensioner she should adapt well. In my opinion if a person still has hand/wrist/arm issues its probably the reach and angle of the bars. Its also pretty tricky to get both bikes speed matched with cruise...
Really no problem with comfort as far as reach, hand and wrist. It is a matter of being even more comfortable. We bought this heritage so we can travel around the country whenever we wish to, me on the EG, her on the Heritage. The idea is to be able to go days on end with shear comfort while visiting all those places we always said we are gonna go too. The kids (4 of them two daughters, Nurses, one son an engineer for John Deer and another in the Army) are grown, graduated from college and out on their own. We the lovely Mrs. Slapp and I are only in our mid 40s and it is our time now. My bike the 09 EG is perfect for me with all the push buttons and do dads, now it is a matter of getting hers done the same way. I want her to feel like this heritage is a recliner going down the road. I know what you are thing... why not a diffrent type of bike or something of that nature. The reason being is because this is the bike she always wanted. In her eyes it is the best of both worlds, cool to look at and ride across town, while at the same time ready to go cross country. Any woman who looks at riding like that, I am going to do my best to make it comfortable for her to do it. This trip to Niagra Falls is only the first of many to come, I want the ride right so we can continue on to countless more journeys.
Thanks for letting me ramble.
May your God Bless each and everyone of you at this wonderful time of the year and please be safe.
Merry Christmas to all and to all a good night.
