We have visited this shop. Its very big and the views so far are right. It all looks middle of the range stuff. They do have a lots of stuff there.
Incidentally, Tiso have 2 discount nights on the 26th Oct and 2nd Nov from 6.30pm - 8.30pm. I do not work for Tiso but thought this may be of help for some on here.
"Its the Rose Street store. Discounts will be 10% of maps, publications and GPS, 15% off practically everything else such as clothing, footwear, rucsacs, tents, accessories and sleeping bags with 20% off all climbing and mountaineering. In addition to this we have some great prices on last season’s models of many ice axes – some of which are half price! All our new Autumn/Winter products are now in stock, so be quick to take advantage of this great opportunity."
