50oz 80/20 twist pile, on premium underlay (I preferred felt when you used to be able to get it) lasts longer than you will with the right maintenance and;
you do not need to Scotch Gard/stain proof it.

Polyprop has come on leaps and bounds in recent years and some are hardly distinguishable now from a Wilton, only problem is oily stain attraction so no good in heavy traffic areas such as receptions and score marks which are beyond restoration.
In a home with young gawd for bids they are brilliant but would still have a medium pile 80/20 over them anytime.
