i am six two and built like a brick out house , and i have had to carry deep langs to and fro when dealing with a commercial operation and it crippled me, if i was to go down the professional route , ie over 40 i would still use smaller frames because not only would i have to buy big exspensive extrators £3800 in total i hear mentioned i would also have to buy evan more equipment so i did not lift them by hand but by machine say another couple of thousand again so thats lots of money spent and for no return, sorry but that dont economical sence to me, we were always told that two small extractors going were easier to to finance than one big one
