The responsive and soft touch are more expensive, There are some threads on here about them can’t remember the exact price but I think the responsive are three hundred and something more and the soft touch are four hundred and something more. If you type in the search bit the threads will come up. I had an uplift with mine and had to stay over night so my price was different to a BA. I think with friend referral discounts and day case you can keep the price reasonable. hope this helps xxx
