content is the reason for price difference . i used to use the Natural one when back in Wales (guessing thats the one on the right) . now up here in Scotland something a little heavier is needed (only my opinion) .
i know of only 2 local fanciers who have chosen to buy the "International" marked rings so they can compete at extreme distance events . ( there may be others ) ?
i am home boys , had a nap , a bath , and a good meal .thank you for the good will messages . slight droop to the face , slower than before , slight slur but home ,,,, for now .
