1. Bend and Snap: Mallets should have some bend in the shaft. While some players want more and some want less there should be enough give for extra oomph. Thus the top 1/2 to 3/4 is generally stiffer and the bottom 1/3 a little more flexible.
2. Intended Use: Indoor and outdoor mallets are slightly. Stiffer shafts and lighter heads work well indoors while heavier heads and a little more flexibility are helpful when outdoors. One could use them interchangeably but people seem to have preferences for lighter and heavier.
3. Budget and Quality: Price and quality are hugely important. $250 dollar mallets have perfect shafts while most players don't need that! One can do equally do well with a $100 mallet that is of durable construction.
Each of us are restricted by our budgets and many new players spend $220 on a mallet they could have got for around half the price! Escanaba Polo Mallet Company offers a Yooper Mallet line that is great for practice for around $100 (check price below). It is rugged, hand crafted and used some hardwood in its construction. A good mallet for practice and clubs. There are discounts if you are buying a few for a polo club or organization. The plan is to donate much of he profits toward social causes like orphans, horse rescue and enrichment causes. Sharing this article is helpful. :) https://www.escanabapolomallet.com/
