IF you plan to store the Nodes on your own storage i don't really think any of them will let you down load a min usually it's all or none but if you use a online Wallet  some have a extention or addon  you can down load the wallet i don't store is the ETC wallet i found this https://www.myetherwallet.com/ it does what mistg or any ETH wallets dopes ,  without the download ......you store every thing but the big download

the ZEC wallets right now are not to bad to down load and store and usually DL fast . i  do keep a updated btc  and Ltc wallet on one of my storage drives on this PC .
