what is the best salt block to use?

Ya i arrowed that buck last year dressed out at 168 he was in full rut as you might be able to see. I was siting in my stand and it was 4:00 and the wind direction was point right where i wanted it to The Swamp. I said to my self all i need right now is a Big buck to come out of the swamp and head right for me. 30 sec later this guy starts walking in right from that direction. He was standing braudside at about 35 yards just looking around ready to beat some one up i pulled back and got ready to aim. Then i noticed he is coming closer. Now i couldnt shoot because of the thickness of the woods. my next shot was going to be a 5 YARD SHOT. That is the hardest shot to do because you have no side view on the deer when your 25 ft up. I still had the bow pulled back and i started to shake holding back 73#. so i bit the bullet and waited for him to step 2 more feet and he will be mine. I took the shot and he took off like a bull. i waited 30 min and couldnt wait any longer the sun was coming down really fast. i started following the blood and 60 yards later i see a nice rack sticking out of the saplings. It was getting dark when i found him by the time i cleaned him out and started pulling it was dark. It was imposible to drag that deer and hold my bow. So every 10 feet i would grab my bow put it down 10 feet away and drag intill i got tangled up in some saplings. I was so tired that i couldnt get it to my truck the last 50 yards there is a very very steep hill i had to call my brother to come and give me a hand and we both had a hard time getting it up.
